Figure 26 is a top plan view of certain parts shown in Figure 13 illustrating a somewhat modified construction there'of. H Inthe embodiment of the invention illustrated by these drawings; a sewing machine is shown having mechanism for feeding buttons into position to be sewed on garments, etc. This sewing machine, of any form or type suitable for this purpose, has a frame I, table 2, arm 3 overhanging the table, shaft 4 with pulleys 5, 6 carrying the driving belt 7, needle'8 carriedby ver-t tically-reciprocating needle bar 9, pressure feet 10 carried by links I l on the foot-raising bar 12, shuttle-operating rod l3, thread-guiding and tensioning devices I4, [5, etc. as indicated in the various views.

Flat buttons I6 are fed along the sewing ma chines table, over the work piece or fabric sheet on which they are to be sewed, in the following manner and by the following mechanismz. A

thin strip I! of suitable material, as sheet metal,

has struck-out tongues 18 thrust through the buttons holes l9 'andbent on the buttons sufficiently to attach the same in spaced relation onthe under side of the strip as shown. Said tongues are sufiiciently rigid to normally. hold the buttons-on the stripas seen in Figure --9, and. at the same time are sufliciently'pliablev to, be bent'as'shown in Figures 10 and3 into position the right-hand pair of laterally spaced parallel parts 40 having releasing the buttons; and the strip is sufficiently pliable to be curved into shapes seen in Figures 1, 3, 5, 6 and 10. This strip is moved to advance the buttons one at a time to sewing position under the needle, and after each button is sewed through one pair of its holes it is automatically advanced a suflicient distance to be sewed through a second pair of its holes.

A pair of parallel arms 55 at the opposite sides of the machines frame are swingably mounted thereon-at 56. The free upper ends of these arms carry a horizontal pivot rod 5'! extending trans A pair.

versely of the machine above its table 2. of laterally-spaced bars 58 turnably and slidably mounted on this pivot rod extend toward the front of the machine. Chains 26 are carried by spaced wheels 22 and 2|, journalledat'BD on these bars respectively and are composed of links 23 connected by links 25. The links 23 are composed of thin upper and lower plates 44 projecting laterally beyond the links 25 andhaving bevelled corners 24. The lower plates 44 are provided at the bevelled corners with angularly disposed flanges 24 extending upwardly at an inclination and forming abutting surfaces located between the upper and lower plates 44 for engaging the button H5 at opposite sides thereof. The button. engaging flanges 24 of the proximate ends of theadjacent links 23 are spaced apart to receive a portion of the buttons l6 between them. Any other suitable means may, of course, be employed for forming the button engaging surfaces.

To feed the buttons successively, the strip H with the buttons attached thereto is moved by suitable means as the pedal 33 (as hereinafter described) toward the left-hand side of Figures 1 and 2 and toward the needle 8 by the travel of the chains 26 whose links 23'engage the buttonsat their'diam'etrically opposite edges; The chains are thus travelled by their wheels 2| rotated step by step by coaxial arms 26 having pawls 2.1 pivoted thereon at 66. and engaging the teeth 26"of the ratchet wheels 29 on the vertical 3110f said wheels 2|. These arms 26, are turned by the rods 3| pivoted to the opposite extensions 32 of arms 26 and moved by suitable means as. by the pedal 33 whose rod 34 is pivotally connected at T6 with the slide bar '15 whose slot lllficontains the lateral pin I05 of one arm 35, of a 'bell crank lever whose other arm 36 is connected to a rod 3'|,having a cross bar 38 on whichthe rods 3| are pivoted.

When the 'strip H has beenthus moved toward the needle to a certain position (best seen in Figures 3 and 10), the buttons are, one at a time, detached from the strip by means shown in said views. Suchfmeans includes a foot member 39 inthe, path of, and above, the moving strip. l1 (best seen in Figures 10, 11 and 12) comprising a upper surfaces 4| curving upwardly (as seen in Figure 10) from their front edges or toes 42, and sideportions 43. In the strips fed movement, these toes engage under the strip and over the buttons, so that the strip slides on the surfaces 4| and is curved upwardly from the buttons thereby bendingthe tongues l8 downwardly and out of the buttons holes to detach the buttons from the moving strip. The curved portion of the strip from which the buttons have been thus detached passesupwardly and rearwardly on the member 39, as shown Figures 1, 3 and 5, to be discarded, whilethe detached buttons are'fed by the links 23 forwardly, into position to be sewed on the fabric work piece by the needle which passes alternately through a pair of the buttons holes, the needles carrying bar 9 being mounted for oscillating movement sidewise of the machine as hereinafter explained.

In this fed movement of the strip I1 and of the buttons detached therefrom, they are guided by the thin top and bottom plates 44 of the links 23 which engage the buttons on their upper and lower sides, said top platesengaging; under the strip as shown in Figures 13 and 14.

In order to position the button-engaging portions of the two chains 20 so that the strip I! will be guided ina direct line to the needle, the outer edges 45 of the plates 44 of such portion of one of the chains slide on a bearing member 46 adjustable relatively to such direct line by its threaded rods 41 having setting nuts 46 engaging the upwardly extending rib 4S; and the outer edges 50 the links 25 of such portion of the other chain slide on the bearing member 46 adjustable relatively to such direct line by its threaded rods 41 having setting nuts 48 engaging the rib 49 and in the second-mentioned chain, shoes engage on the outer edges 45 of the plates 44 of links 23, these shoes being springpressed at 52 into said engagement.

When the sewing through the forward pair l9} of holes has been completed as above described, the bars 58 are moved forwardly a sufiicient distance to bring the rearward pair H! of the same buttons holes into registering position with the needle. Said bars are thus moved automatically by the following means:

A helically-threaded gear or worm 63 on the sewing machines shaft 4 (which operates the needle) meshes with a worm wheel 64 on shaft 65 carrying a cam wheel 66 with a cam groove 61 in its outer side. One of the arms 55 is pivotally connected (for adjustment as hereinafter explained) with one arm 68 of a bell crank lever (fulcrumed on a pivot rod whose other arm 16 has a roll 69 traveling in said cam groove 6].

When the sewing through the forward pair I9 of the buttons holes is going on, the wheel 661s in such turned position that the roll 69 is in the low half 72 of groove 61 thus holding the arms 55, and parallel bars 58 in their rearward position so that the 'needle passes through the forward pair I9 of the buttons holes; but when the wheel 66 turns to the position wherein the roll passes into the high half ll of said groove, the bars 58 are moved forwardly so that. the needle may now pass through the buttons rearward pair of holes la. The machines sewing operation is suspended while the chains 20 are being traveled by theirwheels to present a new button to the needle.

The machines shaft 4 has a cam wheel 11.

(best seen in, Figures 20 and 21) with a side cam 18, a diametrically opposite peripheral cam 19,

and a notch 86in its periphery. This wheel'and,

the shaft 4 are held from turning (and the machines sewing operation is thus held suspended) by a detent 8| urged into this notch by a spring 8'! pressing the detent endwise in its bearing in a block 83 carried by a rock shaft 84. This block has an arm 88 with a lateral pin 89, see Figure 5) engaging in a slot 90 in arm 9| of a bell crank lever whose other arm 92 has a roll Ellitravelingv on the cam periphery 94 of a wheel 95 on the same shaft 65 which carries said cam wheel 66. When permitted so to do, a spring 82 surrounding the.

slidably mounted rod 85 (pivoted at 86 onthe block 83) urges the same outwardly (toward the left-hand side of Figure 5),. V

is, the-sewing through its forwardpair of holes as hereinbefore explained. 75

down to advance a button to the needle and the sewingofthe button has been half finished (that IE! has been finished) while the roll 59 has been traveling in the low half '32 of cam wheelEB and is now about to pass into the high half ll of said 0am to shift the parallel bars'58 forwardly and move the same button to a position to be sewedthrough its rearward pair of holes IS. The cam wheels 66 and 95 thus make one complete revolution for the sewing of any button+half a revolution for sewing through its forward holes I3 and the other half revolution for sewing through its rearward holes l9-during which complete sinjgle revolution the machines shaft 4 and the cam wheel TI thereon revolve many times in the sew-' ing operation.'

The sewing operation having been suspended and the detent 8! being in the notch 89 of cam wheel "H, the sewing operation is resumed. by pressing arm IIliof pedal 33 down which action causes the hook upper end of lever catch 99 (engaging the squared portion of pin 8%) to move arm l 00 downwardly and thus swing block 83 inwardly (toward the right-hand side of Figure 5.) thus moving the detent sidewise out of notch 80 (against the pressure of spring 32) topermit the shaft i to revolve and resume the sewing operation; and the same action caused by pressing pedal arm Iilli also'turns bell crank ill, 92 so as to move roll 93 out of the short low portion 9? of the cam periphery 94 of wheel 95, said roll having 1 been in said low portion while the sewing operaits low point Illfi is reached whereupon the detents outer end I!!! begins to ride up on this wheels peripheral cam I9 (Figures '20, 21). By this time the cam wheel TI has quickly made one revolution and cam wheel 55 has slowly made a sufficient part of one revolution to carry its low.

portion 9'1 away from roll 93 so that this roll may now ride (pedal arm IUI having been released) on the extended high portion 96 of wheel 95 whereby the detent is held from engaging in said notch until another cycle of the machines operation for sewing another'butt'onis initiated by pressing the pedal arm I4 'downwardly'to advance said other button to the needle. When the bar 15 is slid by pedal arm Iii! down far enough, the arm I02 of the catch lever 99 strikes the adjustable threaded stop Iil l and turns the catchlever to its position seen in' solid lines in Figure 5, thus releasing the pin 89, and when pedal arm IEJI is released thecatchlever is raised to position ready to again engage pin 89, and in the meantime roll 93 has passed beyond low part 9'! of cam 94 to hold the detent inthe position seen in Figure 5.

The belt 'I is shifted from the driving pulley 5 to the loose pulley i i-on the machines shaft 4, when the sewing operation is to be suspended and back again when it is to be resumed, by the beltengaging arm Hi8 onthe rockshaft 84 (on which the block 83 is mounted) when said block is swung The needles carryingbar 9 is oscillated side-'- wise of the machine to sew alternately through the holes of either pair 'I9 or I 9 by the following means: The cam wheel Ethas on its inner side a cam groove i I3 in which travels a roll I I4 on the arm i EEcarried by a sleeve Ilii turnable about 7 the pivot rod I I i and in a bearing I I1 in the majoint I22 to a rod 523 which is connected by a flexible joint 52 5 to a lateral extension i25 of an arm I31 pivoted at I38. This rod I23 is turnable in members of these flexible joints and isthreaded in one of them or oppositely threaded in both as seen inFigure 5..

A spindle I39 is slidable in a longitudinal slot Kit in said arm I37 and in a corresponding slot I26 in arm 52? on sleeve H6 which operates the needles oscillation. A hand nut I42 on the threaded outer end of this spindle may be turned to clamp its shoulder I ii on the inner side of arm I2! and thus adjust in the slots the position of the pivotal connection Mil between said arms (see Figure 25). A pointer arm I44 may be provided to indicate on the graduation I45 the position of said pivot. Q

' By moving this spindle-pivot I49 in the slots, the length'oi the movement of rod I23 maybe adjusted to accommodate buttons the holes of whose pairs thereof are spaced at different distances apart. By turning the wheel 65 to a position wherein the roll H4 is midway between any high point IH and'low point I12 of the cam groove H3 (as diagrammatically indicated in Figure 23) and thereupon turning the rod I23 to bring the arms I2'i, :3? to the parallel (vertical) position seen in Figure 5', the oscillation of the needle will be so adjusted that it will move equal distances from the line of feeding extending directly toward the needle and thus the buttons are fed along their center lines toward the needle.

The arms 55 and arm 88 are to be adjusted correspondingly with arms I2? and I3l and by imilar means, as shown in Figures 1, 7 and particularly in Figureslfi and 17. The arm 55 has a longitudinally extending cross-sectionally T- shaped slot 546 vin which is slidable a member Hi1 in which the spindle portion I 48 of a block M9 is turnable at IEiL. The arm 68 has a corresponding longitudinal slot I5I in which is slidable the squared portion I52 of said block. This block is threaded for an adjusting screw I 53 journalled on arm 68. which screw may be turnedto adjust the pivotal connection I itibetween said arms 55 and 68. v

The slot M55 of. arm 55 is open at its bottom I54 so that the block are may be moved downwardly (as indicated in dotted lines in Figure 7) out of this slot by the screw I53 when buttons having only one'pair of holes are to be used on the machine. arms 55 are held against movement by means of a latch pin I55 slidable in a bore I56 in a projection I5lof one of said arms and pressed In this use of the machine, the

The free end I28 of a strip [7 (after the buttons are detached therefrom) may at intervals be severed by shears comprising a fixed blade I29 and a movable blade I30 carried by arm I3I of a bell crank lever whose other arm I32 has a roll I33 traveling on the cam periphery I36 of a wheel I on shaft 65, as seen in Figures 1 and 5.

The parallel arms 58' are not only turnable on the pivot rod 51 but are slidable therealong (so that the chains 26 may yieldingly engage the buttons at their opposite edges) by a spring I63 secured thereto and to the opposite arms of a lever member I64 pivotally mounted at I65 having its opposite arms connected by links I66 to the arms 58 respectively at I5! (see Figure 2). These arms 58 are thus adapted for use with buttons of different diameters. Flexible joints are shown at I68, I69, I18 as well as at I22, I24.

In some cases one of the chains 29 may be dispensed with and in place thereof the buttons may be guided at one edge along a suitable slide bearing H3 as shown in Figure 26.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of any particular embodiment thereof illustrated by the drawings or hereinbefore described.
